Product catalog summary
Overview
The LP980 Transient Absorption Spectrometer is a cutting-edge instrument designed for transient absorption research. It offers unparalleled measurement capabilities, including transient absorption, laser-induced fluorescence, and phosphorescence measurements up to 2.55 µm, with time ranges from nanoseconds to seconds. The dual monochromator/spectrograph allows for both spectral and kinetic acquisition.

Measurement Capabilities
  • Transient Absorption
  • Laser-Induced Fluorescence (LIF) and Phosphorescence
  • Time-Gated Spectra (ns, ms, ms time ranges)
  • Triplet-Triplet Annihilation
  • Reaction Rate Studies

Key Features
  • Dual sample chamber for transient absorption and laser-induced fluorescence
  • High sensitivity with detection limits of ΔOD 0.002 (kinetic) and ΔOD 0.0005 (spectral)
  • Two detectors: Spectral (ICCD) and/or time-resolved (PMT) data
  • Accurate kinetics over 9 orders of magnitude
  • L900 software for comprehensive control of all components and measurements

Specifications
Base Configuration
